Kayla Berg case gets national attention in cable documentary

By  | 

ANTIGO, Wis. (WSAW) -- A nearly 8 year old missing persons case received national attention Sunday after being featured during a cable documentary.

Investigation Discovery aired an episode of "Disappeared" highlighting the case of missing Antigo teen-- Kayla Berg. She was reported missing in August 2009.

Kayla was given a ride to a house on East Wausau Avenue by Kevin Kielcheski-- a friend of her brother. It was reportedly to see an ex-boyfriend Miguel Marrero. But Kayla's friends said Marrero had moved, and Kayla knew that.

Kayla's mother, Hope Sprenger told NewsChannel 7 she wasn't sure how her daughter's story was selected, but did say she had written into the show a few years ago.

The episode highlighted the amount of resources investigators from Langlade County have devoted to the case. Including seeking help from the National Guard in March 2010 to use thermal radar to detect soil disruption by helicopter.

Producers also shared more information about an ex-boyfriend investigators said is no longer cooperating with the investigation-- Miguel Marrero.

"It appears there was an old phone he had registered to him that somehow hit off a tower in the Lincoln County area, north of Merrill," said Sgt. Dan Duley during the episode.

Producers say Marrero said the last time he saw Kayla was about one week before she was reported missing.

Authorities said two short calls were place using that phone about three hours after Kayla was dropped of in Wausau. Call logs show the calls were place at 1:12 a.m. and 2:25 a.m.

Duley said the area where the call would have come from was searched, but nothing was located.

Langlade County also requested the help from a Dane County officer and her cadaver dog. The episode revealed a dozen searches had taken place in wooded areas and fields. The dog showed a reaction to two areas -- Kevin Kielcheski's home in Deerbook and the potato farm where he worked.

"To date, the only thing I can say is my dog continually says is 'the odor of human remains is connected with one person of interest in a variety of different angles to it'," explained Dane County K-9 officer Carren Corcoran.

Kielcheski had once been charged with second degree reckless endangerment for driving Kayla to Wausau and leaving her there, but those charges were dismissed less than two years after they were filed citing lack of evidence.

Berg is described as a white female, 5 foot 2 inches (at time of disappearance), 108 pounds (at time of disappearance), brown hair and brown eyes. Kayla’s ears and navel are pierced. She also has scars on the right side of her nose and on her right shin.

Anyone with information on her whereabouts are asked to call 715-627-6411.
